Concomitant significant mitral regurgitation in patients with aortic valve stenosis undergoing valve replacement: Practical indications

Francesco Lo Iudice, Maurizio Galderisi

Abstract


Significant mitral regurgitation (MR) - either of structural or functional origin - is a frequent condition in patients with severe aortic stenosis (AS), candidate to aortic valve replacement (AVR), and raises the problem whether or not to intervene on mitral valve at the same time. Surgical risk related to the double valve intervention is still significantly higher compared to isolated AVR and international guidelines do not always give definite indications in the presence of multiple valve disease. Furthermore, the increasing diffusion of transcatheter aortic valve replacement for patients at high surgical risk has risen the problem of leaving the concomitant MR untreated. This review is an attempt to give a practical guide for the decision-making process about the treatment strategy of patients with concomitant severe AS and significant MR, analyzing the impact of a persistent MR on prognosis after surgical or transcatheter AVR, the main predictors of MR improvement after isolated AVR - according to the current literature – and displaying the emerging approach involving transcatheter treatment of both AS and MR.
